There is no way to change the enclosure ID in EVA4400. ID assigned for Enclosures are determined by controller and dont have any relation with physical location in the rack.

I've heard from several sources that there is a way, but the information is held back :-(

As far as i know, HP has not published any procedure to change the enclosure ID in EVA4400.

See my answer in this thread:

i.e. ask HP, they can (but I can't promise if they would)...

Well... this is all I can say about this:

1) Yes, it's documented
2) Yes, the enclosure number can be set manually
3) No, it's not public information
4) It must be done before initializing

I'm curious - why can't it be done afterwards?

As far as I can tell, the EVAx400 does soft AL_PAs anyway. And if there are enclosure addressing conflicts (e.g. new enclosure with duplicate ID) this is fixed automatically.

As stated above, the place where it is documented says in red letters not to try it on a working system.
